BLOCK WALLAND METHOD .FOR. 'COLNS'IRU'GTING SAME.

Application filed August 26, 1925.

This invention relates to materials for constructing walls andespecially adapted for use in the construction of buildings.

The main objects of this invention are to provide an improved form ofbuilding block which may be composed of cement, concrete or the like,andformed with appropriate apertures insuch manner that when a wall hasbeen laid up as high as desired, mortar or similar binder can be pouredin the openings which are provided in the blocks, one opening above theother in mutual registry to seal and bind them together; to providemolded blocks of improved form adapted for light and economicalconstruction and having suitably arranged cavities, apertures andperforatory openings for the admission of interlocking means, binders,and reinforcing elements, and for air filled heat insulating spaces, asmay be variously required in accordance with specific needs.

An illustrative embodiment of this invention is shown in theaccompanying drawings in which Figure 1 is a plan view of a blockadapted to accommodate the use of a thin strip of water-proof insulatingmaterial between successive courses to cover the air cavities and keepout surplus binder.

Fig. 2 is an end view of the block shown in Fig. 1.

Fig. 3 is a bottom plan of the block shown in Fig. 1.

Fig. 4 is a vertical section through a wall taken on the line 2222 ofFig. land showing a protective strip bet-ween courses.

Fig. 5 is a side elevation of a block such as shown in Fig. 1.

Fig. 6 is a section on the line 2424 of Fig. 1.

In the first place, when the foundation is laid it must be perfectlylevel. Then the blocks are laid one above the other, with appropriateapertures, in substantially perfect alinement. The mortar for bindingthe blocks together is mixed to a thin, .soupy consistency. The holesinto which the mortar is poured all connect up evenly with each other,and the mortar serves to bond them firmly and evenly together. The wallmay be built as high as desired before pouring in the concrete.

As compared with ordinary concrete constructions for walls andbuildings, these Serial No. 52,570.

blocks have certain very desirable advantages, including mainly thatthey eliminate theneed of .askilled mason; they have..at least as goodorbetter.durabilitythan any 'ot'herlbuilding cementitiou s block; theycan 'Lbemoulded very. readily and rapidly, as, for

instance, three blocks can be made .in .one minute in a stripper powermachine; there are numerous, for instance, eight, rivet-like bindersgoing down through the entire height of the Wall; the wall is thoroughlytight and has a double seal, inner and outer, whereby the wall is tightand heat insulated, as well as substantially sound proof.

These blocks are intended to be used principally in cases where stuccois used on the outside, as it is cheaper to make this block in the roughthan it is to put a smooth or fancy face on it.

111 the construction shown in the drawings, a block 43 formed preferablyby a molding process with apertures 46 and 47. adapted to receive meansfor locking the blocks together when in place and with a series ofrectangular air chambers 45 which are open at the top and bottom forrendering the block light in weight. The apertures 46 and 47 are alsoadapted to receive reinforcing means such as metal bars 15 if desired.Vertical end grooves 64: are provided in which binder is poured when theblocks are set up end to end. The'bottom face is flat and is bordered bylateral semicircular grooves 59 and depending side flanges 60 and thebearing faces 61.

Lateral branches of binder extending lengthwise of the block areprovided for by forming grooves 59 extending from opposite sides ofholes 47, on the under side of the blocks, said grooves being brokenmidwa between the holes by cross walls 66 whic are of less height thanthe depth of the grooves 59. The cross walls prevent the binder fromflowing across to the next adjacent hole. Thetop face 54 is flat andbordered by inclined shoulders 55 and edge bearing faces 56.

The ends are formed with alined middle faces 62 and edge faces 63separated by the grooves 64 for binder. The middle face portions 54 and58 are spaced apart sufficiently to accommodate a shield strip 41without taking more than nominal pressure, the edge faces 56 and 61being relied upon to carry the load and maintain wall stability.

In order to show the details clearly, the blocks are spaced apartslightly in Figs. 4 and 6.

In laying up the wall, as soon as a course of blocks is set in place, astrip 41 is laid thereon to cover all of the holes 45, care being takenthat it does not overlap any of the binder holes 46 and 47. The shield41 may be of felt-like material so as to yield somewhat and assure atight gasket-like fit. This feature enhances heat insulation by closingoff air cavity 45. Such a Wall is warm in winter and cool in summer.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that details of theconstruction shown may be altered August. 1925.
